enum rename_fk: Replaces the "bool use_fk" parameter of
row_rename_table_for_mysql() and innobase_rename_table():
RENAME_IGNORE_FK: Replaces use_fk=false when the operation cannot
involve any FOREIGN KEY constraints, that is, it is a partitioned
table or an internal table for FULLTEXT INDEX.
RENAME_REBUILD: Replaces use_fk=false when the table may contain
FOREIGN KEY constraints, which must not be modified in the data
dictionary tables SYS_FOREIGN and SYS_FOREIGN_COLS.
RENAME_ALTER_COPY: Replaces use_fk=true. This is only specified
in ha_innobase::rename_table(), which may be invoked as part of
ALTER TABLE…ALGORITHM=COPY, but also during RENAME TABLE.
An alternative value RENAME_FK could be useful to specify in
ha_innobase::rename_table() when it is executed as part of
CREATE OR REPLACE TABLE, which currently is not an atomic operation.
